GILL-BOX AND GILL-DRAWING FRAME.

Application filed May 7, 1.907.

Specification of Letters Patent.

Patented June 9, 1908.

Serial No. 372,672.

To all whom it may concern:

Be it known that I, WILLIAM IIOLDSWORTII, a subject of the King of GreatBritain and Ireland, and a resident of Halifax, Yorkshire, England, haveinvented certain Imrovements in Gill-Boxes and Gill-Drawing rames, (forwhich I have obtained a patent in Great Britain, No. 22,136, bearingdate October 8, 1906,) of which the following is a specification.

This invention relates to gill boxes and gill drawing frames and itconsists in the novel construction and combination of the partshereinafter fully described and claimed.

In the drawings, Figure 1 is a front view of the apparatus. Fig. 2 is across-section taken through the parts 23, 27 and 28 on the line A-B inFig. 1, and looking in the direc* tion of the arrow. Fig. 3 is an endview of the apparatus showing the shaft 2 in section. Fig. 4 is avertical section through the rollers of the apparatus. Fig. -5 is adetail view of one of the bearings 10.

28 is a supporting base-plate provided with bearings 27 2 is the maindriving shaft of the apparatus which is journaled in the bearings 27,and provided with a wheel 38, or any other approved means, for revolvingit.

1 is a smooth cylindrical bottom roller which is secured on the shaft 2.

24 are bearing blocks which are pivoted on the shaft 2, and 16 are sidebars which are secured to the said blocks 24 at their lower ends.

16 are bearings which are adjustably secured on the screwthreaded upperend portions of the bars 16, and 17 are nuts for looking the saidbearings in position. An upper roller 15 is journaled in the saidbearings 16 28 is a crossbar, the end portions of which have holes whichare slidable over the lower portions of the bars 16, and 18 are springswhich press the said crossbar downwardly.

19 are wheels which are screwed on the middle parts of the bars 16 andwhich afford a means for adjusting the tension of the springs 18, and 20are nuts for locking the said wheels to the said bars.

22 are bearing-blocks which are secured to the crossbar 23 and which areprovided with hearing grooves 21. A lower roller 3 provided with a shaft6 is journaled in the bearing grooves 21, and 7 is. an endless a ronorleather which passes over the said r0 lers 15 and 3, and which ispressed downwardly toward the roller 1 by the springs 18.

26 are set-screws which are slidable in curved slots 27 in thebearing-blocks 24, and which are screwed into the stationary bearings27. The bars 16 and the parts carried by them form a frame which can beadjusted circumferentially toa limited extent about the shaft 2, andwhich can then be secured in position by the set-screws 26.

4 are toothed wheels which are secured on the shaft 2, and which gearinto toothed wheels 5 secured on the shaft 6, so that the roller 3 isdriven positively and in the opposite direction from the roller 1. Theroller 1 is preferably smooth, and the roller 3 is preferably roughened,and the endless apron or leather 7 is driven by contact with the saidrollers as it passes between them. The fallers 14 are arranged to oneside of the rollers 1 and 3, and the material passes from the saidfallers between the apron 7 and the roller 1 as shown in Fig. 4. k

9 is a small licker-in roller arranged between the fallers and theroller 3. The roller 9 is journaled in bearings 10 on the upper ends oftwo similar standards 10 which are slidable vertically in guide brackets1 1. The guide brackets 11 are secured to the base 28, and are providedwith springs 8 which bear on nuts or collars 13 secured on the saidstandards 10, so that the roller 9 is pressed upwardly against thematerial.

29 is a spring scraper which is adjustably secured to the base 28 byfastening devices 31. The sharp edge of this scraper bears against theroller 1, and prevents the material frorn winding around it.

What I claim is:

1. The combination, with a bottom roller provided with means forrevolving it, of circumferentially adjustable side-bars pivotedconcentric with the said bottom roller, means for securing the saidsidebars in position, an upper roller carried by the said side-bars, aslidable spring-pressed crossbar also carried by the said side-bars, alower roller bearing in the said crossbar, and an endless a ron passingover the said upper and lower ro lers and operating to press thematerial against the said bottom roller.

2. The combination, with a bottom roller provided with means forrevolving it, of circumferentially adjustable side-bars pivotedconcentric with the said roller, means for securing the said side-barsin position, a slidable spring-pressed. crossbar carried by the saids1debars, a lower roller bearing in the said crossbar, toothed driving;wheels operatively connecting the said lower roller with the said bottomroller, and an endless apron passing over the said upper and lowerrollers and o perating to press the material against the said bottomroller.

3. The combination, with a base provided with stationary bearings, 01' ashaft journaled in the said bearings and provided with means forrevolving it, a bottom roller secured on the said shaft, acircumferentially adjustable frame pivoted on the said shaft andprovided with means for securing it to the said bearings a pair ofrollers journaled in the said frame, and an endless apron passing overthe said pair of rollers and operating to press the material against thesaid bottom roller.

4. The combination, with a stationary support, and a bottom rollerjournaled therein and provided with means for revolving it; of a pivotedframe which is adjustable circumferentially of the said bottom roller, apair of rollers bearing in the said frame, and an endless apron earriedby the said pair of rollers and o erating to press the material againstthe sald bottom roller.

5. The combinz-ttion, Wit] 1. a stationary support, and a bottom rollerournaled therein. and provided with means for revolving it; of

a pivoted frame which is adjustable circumferei'itially of the saidbottom roller, a pair of rollers bearing in the said, frame, an endlessapron carried. by the said. pair of rollers and operating to press thematerial against the said bottom roller, l'alle'rs arranged to one sideof the said. bottom roller, and a springpressed liclcer-in rollerarranged intermediate of the said lallers and. the said apron orleather.

6. The coinbii'iation, with a stationary support, and a bottom rollerjournaled therein and provided with means for revolviii e it of apivoted frame which is adjustable circumferentially of the said bottomroller, a pair of rollers bearing in the said frame, an endless aproncarried by the said pair of rollers and operatii'ig to press thematerial against the said bottom roller, and a scraper which bears onthe said bottom roller.

In witness whereof I have hereunto set my hand in presence of twoWitnesses;

'WILLIAM HOLDSWORTH.
